What's really pissing me off about Dazzler's return to the X-Men is that Dazzler hasn't returned to the X-Men. Solicits and promo art have made such a big deal out of Dazzler's return, but she hasn't actually done anything. So far, she's popped up in Uncanny X-Men to perform some music in Oakland and visit Pixie in the X-Center's infirmary.
The editorial team went through all the trouble of nudging Simone Bianchi into designing a new costume for her, and she's been shown wearing it for no reason. "Oh, I'm going to visit that little pink-haired girl who got beat up. I'm going to slip into the brand new X-Men outfit just for this visit, without actually joining in the effort to track down the thugs who beat up this kid right outside of one of my shows."
You can tell when a character just doesn't need to be there when Karma's been shown doing more. Karma, people.
